Does Left ventricular outflow tract velocity time integral outperform ejection fraction and Doppler-derived cardiac output for predicting adverse outcomes in a select advanced heart failure cohort?
Extremely low LVOT VTI is a superior predictor of adverse outcomes compared to ejection fraction and Doppler-derived cardiac output in advanced heart failure, helping identify candidates for advanced therapies.
Extremely low LVOT VTI strongly predicts adverse outcomes and identifies patients who may benefit most from advanced heart failure therapies.
